Folliculitis: pimple-like, painful bumps on the scalp

Folliculitis may look like small red or pus-filled pimples centred on hairs. Tenderness can follow friction from helmets, tight headwear, scratching, shaving, or heavy hair products. Itching may occur alongside pain. Similar-looking bumps can also reflect ingrown hairs, acne, or another scalp condition, so appearance alone cannot confirm the cause.

Do not squeeze the bumps. Breaking the skin can spread irritation to nearby follicles and may leave crusting or temporary marks. A clinician can inspect the scalp and decide whether testing or prescription treatment is appropriate.

Wash gently with lukewarm water and a mild cleanser, then pat the scalp dry. Pause oils, pomades, and fragranced products that touch the affected area. Avoid picking, close shaving, and tight hats until the skin settles; wash items that contact the scalp regularly. Do not share combs, brushes, or towels.

If a clinician identifies a bacterial infection, treatment may include a prescribed topical medicine or oral antibiotics; these are not interchangeable and should not be started from leftover medication.

Arrange an appointment if the bumps keep returning, spread, drain, form thick crusts, or do not improve with gentle care. Seek prompt assessment for rapidly increasing pain, marked swelling, fever, feeling unwell, or tenderness extending beyond the original area. Earlier review is sensible if you have reduced immune defences or significant scalp disease.

Ask whether the pattern fits folliculitis, an ingrown hair, acne, or another cause; whether a swab is needed; which products or grooming habits may be contributing; and how long to use any prescribed treatment.
